Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof cabinets, in particular to a closed explosion-proof energy-saving power distribution cabinet. Background Art

[0002] Distribution cabinets, boxes in which electrical appliances and their circuits are placed, are used to distribute electrical energy. Collectively referred to as power distribution centers. They are centrally installed in the enterprise's substation to distribute electrical energy to lower-level distribution equipment at different locations. With the rapid development of industries such as petroleum, chemical, military, engineering, factories, mines, and mining, explosion-proof distribution boxes are increasingly used in production, storage, and rescue, with more and more varieties. How to prevent accidental explosions of explosion-proof distribution boxes in explosive gas hazardous places has become a very important topic. Since explosion-proof distribution boxes inevitably generate electric sparks during operation, once they encounter explosive gas mixtures at the production or rescue site, explosion accidents will occur, directly endangering national property and the lives of citizens. Therefore, as the most widely used distribution system, its explosion-proof technical issues have long attracted widespread attention and high attention.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing enclosed explosion-proof energy-saving distribution cabinets do not have good heat dissipation function. Since most of these energy-saving distribution cabinets are enclosed in design, the devices run inside them, which is prone to insufficient heat dissipation, indirectly affecting the service life of the energy-saving devices. Improvement is urgently needed. Therefore, we propose a enclosed explosion-proof energy-saving distribution cabinet. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1-3 The utility model provides a technical solution: a closed explosion-proof energy-saving power distribution cabinet, including a cabinet 1, a plurality of groups of brackets 15 in a uniform array are fixedly installed on the rear inner wall of the cabinet 1, and supports 13 are fixedly installed at the four corners of the bottom of the cabinet 1. Positioning holes are opened on both sides of the support 13 and on both sides of the front wall of the bracket 15. The cabinet 1 can be stably limited by the support 13 and its positioning holes. At the same time, the bracket 15 and the positioning holes are used for the assembly of energy-saving devices. A cabinet door 2 is placed on the front side of the cabinet 1, and a gantry 4 is placed on both sides of the cabinet 1. Sleeves 3 are placed on the inner sides of both ends of the gantry 4; the cabinet door 2 is rotatably connected to the front side of the cabinet 1 through a hinge, and a lock body 21 is fixedly installed on the front side of the cabinet door 2. The lock tongue of the lock body 21 is stuck in the lock buckle 11, and the lock buckle 11 is fixed on the cabinet 1. The cabinet door 2 can be closed tightly by the cooperation of the lock body 21 and the lock buckle 11, which is used for the stable limit of the cabinet door 2, meeting the needs of the product. The cabinet 1 is connected to the bottom thereof with a plurality of wire tubes 12 in a uniform array, and sealing rings are fixedly installed in the wire tubes 12, and openings 14 are provided on both side walls of the cabinet 1; the sleeve 3 is fixedly connected to the cabinet 1, and the end of the gantry 4 is detachably fixed in the sleeve 3; a driving motor 42 is fixedly installed in the middle of the outer side of the gantry 4, and a handle 41 is fixedly installed on the outer side of the gantry 4 close to the driving motor 42, and an anti-slip sleeve is fixedly installed on the handle 41, and the gantry 4 can be moved by holding the handle 41, which is convenient for force disassembly and assembly, and the anti-slip sleeve can improve the grip comfort and friction, a fan blade 43 is fixedly installed on the inner end of the transmission shaft of the driving motor 42, and bead grooves 44 are provided on both sides of the two ends of the gantry 4; cross bars 5 are fixedly installed on both ends of the inner side of the gantry 4, an aluminum plate 51 is fixedly installed on the inner end of the cross bar 5, a sealing pad 52 is fixedly installed on the inner side of the aluminum plate 51, and the aluminum plate 51 is positioned at the opening 14.

[0024] In this technical solution, the opening 14, the aluminum plate 51 and the fan blades 43 and other components can be used together. During the use of the closed explosion-proof energy-saving distribution cabinet, due to the setting of the aluminum plate 51 and the good thermal conductivity of the aluminum plate 51, the fan blades 43 can be driven by the driving motor 42 to rotate at high speed and blow air toward the aluminum plate 51. The aluminum plate 51 extracts the heat in the cabinet and can dissipate the heat of the sealed cabinet well, which is beneficial to improving the life of the internal components. At the same time, the gantry 4 can be detachably assembled, and the heat dissipation mechanism can be moved, replaced, inspected and recycled separately at a later stage. After the aluminum plate 51 is disassembled, the personnel can stand at the opening 14 or extend their arms through the opening 14 to touch the side of the device, which is convenient for the later inspection, cleaning and replacement of the device.

[0025] In some technical solutions, through openings 31 are opened on both sides of the sleeve 3, a horizontal plate 33 is fixedly installed in the through opening 31, a T-shaped rod 32 is movably passed through the horizontal plate 33, a semicircular head 35 is fixedly installed at the inner end of the T-shaped rod 32, and the semicircular head 35 is abutted in the bead groove 44, and a spring 34 is sleeved on the outer side of the T-shaped rod 32.

[0026] In this technical solution, the semicircular head 35 and the spring 34 and other components can be used together. The spring 34 can be used to give the semicircular head 35 a force to make it resist and be stuck in the bead groove 44. If the gantry 4 needs to be disassembled later, the gantry 4 can be moved outward by applying force, the semicircular head 35 can be adaptively extended and retracted, and the spring 34 can be adaptively moved, and the detachable gantry 4 can be disassembled. Conversely, pressure can be applied to the position to achieve the reinstallation limit of the gantry 4.

At the same time, the gantry 4 can be detachably assembled, and the heat dissipation mechanism can be shifted, replaced, repaired and recycled separately in the later stage. After the aluminum plate 51 is disassembled, personnel can stand at the opening 1 4 or the arm is passed through the opening 14 to touch the side of the device, which is convenient for the later inspection, cleaning and replacement of the device. By providing a semicircular head 35 and a spring 34, the semicircular head 35 can be given a force by the spring 34 to make it resist and be stuck in the bead groove 44. If the gantry 4 needs to be disassembled in the later stage, the gantry 4 can be moved outward by applying force, the semicircular head 35 is adaptively extended and retracted, the spring 34 is adaptively moved, and the detachable gantry 4 is disassembled. Conversely, pressure is applied to the position to realize the reinstallation limit of the gantry 4. The limit structure is easy to disassemble and assemble in the later stage, without complicated procedures, and the use effect is relatively ideal.
